[0002] With the progress and development of society, the quality requirements and environmental protection requirements for spraying anti-corrosion paint on the inner wall of pipelines are getting higher and higher. In the existing process of spraying the inner wall of pipelines, there is a situation where the paint is scattered all around and pollutes the environment. It is necessary to prevent the spraying work from being carried out in a sealed box, but there are certain difficulties in the installation and placement of the pipeline before spraying. In the process of setting baffles at the left and right ends of the pipeline for sealing, there is excess paint accumulated on the pipe mouth parts at both ends, resulting in the thickening of the paint layer on the pipe mouth parts. In addition, for the spraying of pipelines with different radii, the position of the paint spray nozzle cannot be changed adaptively, resulting in the need to adjust the spray range of the nozzle, which is time-consuming and labor-intensive.

[0018] Embodiment 1:

[0019] Reference Figure 1-Figure 7According to an embodiment of the utility model, an inner pipe wall anticorrosive paint layer spraying station includes a spray pipe 10, and sliding platforms 11 are provided at both ends of the spray pipe 10. The sliding platforms 11 are connected to each other or away from each other through a synchronous transportation device. The close ends of the two sliding platforms 11 are slidably connected to two upper and lower symmetrical abutting arc plates 12. A guide slide groove extending up and down is opened on the sliding platform 11. A sliding plate is connected to the abutting arc plate 12 and slides with the guide slide groove. An electromagnetic telescopic mechanism is connected between the guide slide groove and the sliding plate. A sliding arc plate 25 is connected between the two adjacent abutting arc plates 12. The abutting arc plate 12 and the sliding arc plate 25 can abut against the spray pipe 10. A first fixed platform 20 is fixed on the two sliding platforms 11. A power motor 21 is fixed at the close ends of the two first fixed platforms 20. The two first fixed platforms 20 are rotatably connected to two front-to-back symmetrical gears 22. The two power motors 21 are respectively connected to one of the two gears. The gears 22 are connected in power, and the two adjacent gears 22 are meshed with each other. Each gear 22 is fixedly connected with a fixing rod 23 through a shaft rod, and an electric wheel 24 is arranged on the fixing rod 23. The lower end of the abutting arc plate 12 at the lower end is connected with a telescopic material receiving box 19 which can be telescopic up and down. The abutting arc plate 12 at the lower end is provided with evenly distributed openings 18, and the openings 18 are opened up and down and communicate with the telescopic material receiving box 19. The left and right abutting arc plates 12 are fixed with a second fixed platform 13, and a sliding cavity 16 is provided between the two second fixed platforms 13. The two sliding cavities 16 are slidably matched with a support rod 15, and a paint spraying tube 14 is connected between the two adjacent support rods 15. The paint spraying tube 14 is provided with evenly distributed paint spraying ports 17, and the support rod 15 and the paint spraying port 17 are arranged in the same direction. A stepping motor is provided at the second fixed platform 13 on the left side to be power-connected with the support rod 15, and a push spring is connected between the support rod 15 and the sliding cavity 16;

[0020] The pipe to be sprayed 10 is placed horizontally, and the left and right sliding platforms 11 are synchronously controlled to approach each other through a synchronous transportation device, such as a bidirectional threaded rod, so that the electric wheel 24 located at the lower end of the sliding platform 11 abuts against the pipe to be sprayed 10. The position of the electric wheel 24 is adjusted by the power motor 21. When the power motor 21 is powered on, the gear 22 connected to the power is driven to rotate. Under the meshing of the two gears 22, the front and rear adjacent fixed rods 23 are synchronously controlled to adjust the angle, thereby changing the position of the electric wheel 24. The upper and lower heights of the pipe to be sprayed 10 are adjusted by the electric wheel 24, so that the pipe to be sprayed 10 with different radii can be coaxially arranged with the sliding platform 11. The electric wheel 24 part can also be installed on the upper end of the sliding platform 11, so that the electric wheel 24 clamps the pipe to be sprayed 10 symmetrically up and down, thereby improving the stability and coaxiality of the pipe to be sprayed 10. The stepper motor at the second fixed platform 13 on the left side is operated to control the rotation of the support rod 15, such as Figure 5As shown, the stepper motor controls the support rod 15 to rotate counterclockwise by ninety degrees and abut against the inner circumference of the pipe to be sprayed 10. During the abutment process of the support rod 15, due to the change in the radius of the different pipes to be sprayed 10, the support rod 15 can overcome the spring force and slide at the sliding cavity 16 to maintain the spacing between the paint spraying tube 14 and the inner circumference of the pipe to be sprayed 10, so that the spacing is consistent with the length of the support rod 15. The suction pump at the outer end works to extract the spray material in the digging material box into the paint spraying tube 14, and spray the paint on the inner circumference of the pipe to be sprayed 10 through the paint spraying port 17 at the paint spraying tube 14. Through the opening 18, the ingredients located on the left and right sides of the pipe to be sprayed 10 are opened up and down through the opening 18 to enter the telescopic receiving box 19 for collection. The electric wheel 24 is energized to work, so that the wheel at the electric wheel 24 rotates, and the abutment between the wheel and the pipe to be sprayed 10 drives the abutting pipe 10 to be sprayed circumferentially.

[0021] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
